Science redefines coffee benefits

Many scientific studies indicate that consuming one cup of coffee daily is associated with potential health benefits, including a reduced risk of chronic diseases such as heart disease, type 2 diabetes, and neurological conditions like Alzheimer's and Parkinson's. Coffee may also help improve cognitive performance, decrease inflammation, and protect the liver, especially when consuming between one to three cups per day. However, experts caution that excessive intake could lead to side effects such as sleep disturbances and anxiety.
